Haff value quality testerIntroduction
The Haff value of eggs is an indicator specified by the US Department of Agriculture's egg standards for testing and indicating the freshness of eggs. Currently, this indicator is also used in China, and it is mainly divided into four levels: AA - level: 72 or higher; A-grade: 71-60; B-level: 59-31; Grade C: 30 or lower;
The calculation formula for the Haf unit is Ha=100 * lg [h+7.57-1.7 * (w60 ^ 0.37)], where h (mm) is the height for measuring concentrated protein and w (g) is the mass for measuring eggs.
Main technical features
Using a digital display to show the height value of concentrated protein and eggshell thickness.
L can detect protein height and eggshell thickness at any position
The small LCD screen clearly displays the test results for easy recording
Measurement range: 0.00-11.00mm
Detection accuracy: 0.01mm
The digital display of the balance weighing device has a weighing range of 0-200g and an accuracy of 0.01g.
Equipped with data calculation software, input protein height and weight, and automatically calculate the Haff value.
